Emerging wireless remote sensing technologies offer significant potential in advancing the management of construction processes by providing real-time access to the locations of workers, materials, and equipment. Unfortunately, little is known regarding the reliability and practical benefits of emerging sensing technology integrated with Building Information Modelling (BIM) within an indoor bui...

The United States Navy (USN) is shifting towards condition-based maintenance (CBM) of fatigue critical dynamic components on rotorcraft, which requires more efficient methods for component identification, usage history recording, and fatigue life tracking. This paper presents a method developed by Technical Data Analysis, Inc. (TDA) to track usage and history of all uniquely serialized componen...

Knowing the locations and paths of individual mice is important for behavioural analysis of large groups of laboratory mice. Traditional observations are carried out by trained humans who are able to distinguish more than 50 behavioural patterns. A tedious labour limited with respect to observation length. In this paper an RFID (Radio Frequency Identification)based tracking solution is presente...

This paper presents the speaker tracking system of the LIA laboratory, validated during ESTER 2005 campaign on a radio broadcast news corpus of about 90 h. The LIA speaker tracking system firstly uses an acoustic class segmentation in order to suppress non speech frames and to detect the speech conditions. Secondly, a speaker diarization process is applied in order to provide speaker detection ...

Radio Frequency Identification (RFID) systems promise large scale, automated tracking solutions but also pose a threat to customer privacy. The tree-based hash protocol proposed by Molnar and Wagner presents a scalable, privacy-preserving solution. Previous analyses of this protocol concluded that an attacker who can extract secrets from a large number of tags can compromise privacy of other ta...

The use of Radio Frequency Identification (RFID) technology extends historically to the 1970’s, when the first commercial products emerged. The introduction of this technology motivated future research that sought to integrate RFID into various applications ranging from inventory control/monitoring to human/animal tracking. However, the practical significance of this technology was not fully re...

Displacement estimation is a key step in the evaluation of tissue elasticity by quasistatic strain imaging. An efficient approach may incorporate a tracking strategy whereby each estimate is initially obtained from its neighbours' displacements and then refined through a localized search. This increases the accuracy and reduces the computational expense compared with exhaustive search. However,...

The TIDGET® is a low power GPS tracking device that is being developed by NAVSYS under contract to the US Army. This TIDGET tracking device uses a client/server approach to send raw GPS sampled data to the TIDGET Location Server through a wireless data link. The TIDGET Location Server is based on a Software Defined Radio architecture and uses a GPS waveform application to process the GPS sample...

The escalating scale and growing complexity of ready-mixed concrete (RMC) delivery operations have challenged current methods for monitoring RMC delivery and dispatching truckmixers by two-way radio voice-based communication and experience-driven management. This paper describes an integrated navigation system, based on Global Positioning System (GPS)/Dead Reckoning (DR)/Bluetooth Beacon (BB) a...

Software-based GPS (SGR) Receiver helps us processing the GPS signal at the lowest level of GPS raw signal data from the antenna. A software-based GPS receiver consists of a front-end device that converts the radio frequency signal from the antenna to an intermediate frequency in digital format. The signal thus converted is processed by high level programming language to compute position and ve...
